VERTICAL ASYMPTOTES

The line x=L is a vertical asymptote of the function , if the limit of the function (one-sided) at this point is infinite.

In other words, it means that possible points are points where the denominator equals 0 or doesn't exist.

So, find the points where the denominator equals 0 and check them.

As can be seen, there are no such points, so this function doesn't have vertical asymptotes.
